Current R&R by category
Whole-project rollup at the latest vintage per category: printed project-level rows are preferred, and mining areas are summed (tonnes-weighted grade) only where the issuer prints no project-level row. Per-area and per-source detail in the Current R&R table below.

Rows are hierarchical, not additive — do not sum a column across rows. Whole-project rows (Area “Total”) already contain the indented named-area rows beneath them, and an issuer's printed per-deposit total can itself contain other listed areas. All derived totals and rollups on this site already exclude the overlapping rows.
